Apparatus and method of removing carrier from a recording element
View Patent ↗An apparatus and method of removing carrier from an article are provided. The apparatus includes a heater positioned to direct heat toward an article travel path. The heat has an emission spectrum with a peak emission wavelength and the carrier having an absorption spectrum with a peak absorption wavelength. The peak emission wavelength of the heat substantially corresponds to the peak absorption wavelength of the carrier.
1. A carrier removal station comprising:
a heater positioned to direct heat toward an article travel path, the heat having an emission spectrum with a peak emission wavelength, the carrier having an absorption spectrum with a peak absorption wavelength, the peak emission wavelength of the heat substantially corresponding to the peak absorption wavelenth of the carrier,
wherein the heater comprises:
a first heating element having a length L 1 , the length L 1 extending along a maximum width of the article travel path, the article travel path defining an article travel direction;
a second heating element having a length L 2 , the length L 2 being less than the length L 1 , the second heating element being positioned parallel to the first heating element and spaced apart from the first heating element relative to the article travel direction of the article travel path, one end of the second heating element being aligned with one end of the first heating element; and
a third heating element having a length L 3 , the length L 3 being substantially equal to the length of the second heating element L 2 , the third heating element being positioned parallel to the first heating element and axially aligned with the second heating element one end of the third heating element being aligned with a second end of the first heating element.
2. The carrier removal station of claim 1 , wherein the first heating element is positioned at a first distance relative to the article travel path, and the second heating element and the third heating element are positioned at a second distance relative to the article travel path, the second distance being equal to the first distance.
3. The carrier removal station of claim 2 , wherein the first heating element is operable at a first voltage V 1 , and the second heating element and the third healing element are operable at a second voltage V 2 , the second voltage being higher than the first voltage.
4. In a carrier removal station having a heater positioned to direct heat toward an article travel path defining an article travel direction, the heater comprising:
a first heating element having a length L 1 , the length L 1 extending along a maximum width of the article travel path, the article travel path defining an article travel direction;
a second heating element having a length L 2 , the length L 2 being less than the length L 1 , the second healing element being positioned parallel to the first heating element and spaced apart from the first healing element relative to the article travel direction of the article travel path, one end of the second heating element being aligned with one end of the first healing element; and a third healing element having a length L 3 , the length L 3 being substantially equal to the length of the second healing element L 2 , the third healing element being positioned parallel to the first healing element and axially aligned with the second heating element, one end of the third healing element being aligned with a second end of the first healing element.
